1.8" Gemmy Aquamarine Crystal with Muscovite - Pakistan

This is a pristine, gemmy, sky-blue aquamarine crystal cluster with muscovite from Baltistan, Pakistan. The specimen features several lustrous, aquamarine beryl crystals that have formed in association with muscovite crystals.

Aquamarine is a blue-green variety of beryl. Oddly enough, it owes its color to iron(II) and iron(III) cations within the crystal lattice, of which iron(II) is responsible for the blue color, while iron(III) is responsible for the yellow color. The color vibrance and hue are dependent on the concentration of these cations, or lack of one or the other. The presence of both cations in the right position within the crystal lattice, can result in a deep blue colored crystal that is known as "maxixe".

Muscovite is a phyllosilicate mineral of aluminium and potassium. It has a highly perfect basal cleavage yielding remarkably thin laminae which are often highly elastic.
